This GRUNDIG UV5A Owner Manual is not only an instruction manual but a total functional circuit description of the Multimeter and includes circuit diagram at the end pages. It is very helpful for repairing and calibrating the instrument. It is written in two languages English and German for international support. It was very easy to repair my unit with this document. Regards, Regis Pauly, Electrical Engineer.
The owner's manual was evetything I thought it would be. I was able to print it out using both sides of the paper in quick order, saving me a search online for a used one.
Fantastic quality and impressive delivery time. Based on this manual, I recommend this service without hesitation! Five Stars for certain.

Pressure Testing
Remove the pan supports and the burner caps and crowns. The pressure testing must be carried out on the burners. Proceed as follows: 1. Fit manometer tube over the injector. 2. Turn on the burner gas supply and ignite another burner. 3. The pressure reading should be nominally 20 mbar and must be between 17 mbar and 25 mbar. 4. Turn off the burner supplies.
Conversion from Natural Gas to LPG
It is important to note that this model is designed for use with natural gas but can be converted for use with butane or propane gas providing the correct injectors are fitted. The gas rate is adjusted to suit.
Method
1. Ensure that the gas taps are in the 'OFF' position 2. Isolate the hob from the electrical supply 3. Remove all pan supports, burner caps, rings, crowns and control knobs. 4. With the aid of a 7mm box spanner the burner injectors can then be unscrewed and replaced by the appropriate LPG injectors (see "Characteristics of gas burners" on the next page).
To adjust the gas rate
With the aid of a thin bladed screwdriver completely tighten down the by pass adjustment screw. Upon completion affix the replacement rating plate on the under side of the hob.
IMPORTANT
The replacement/conversion of the gas hob should only be undertaken by a competent person.
